Advanced Management of Acute Intermittent Porphyria: The Role of Givosiran Therapy in Improving Long‐Term Outcomes‐A Case Study

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Acute intermittent porphyria is a rare disorder causing neurotoxic precursor accumulation and severe neurological complications. We report a case progressing to tetraplegia and respiratory failure with delayed diagnosis. Treatment with hemin and givosiran resulted in prevention of attacks and functional recovery, highlighting the importance of

Successful Treatment of Anemia With Ringed Sideroblasts Induced by Antidepressants Through Vitamin B6 Supplementation and Discontinuation of Antidepressants

Case Reports in Hematology
Vitamin B6 (VB6) is a vital coenzyme for δ-aminolevulinic acid synthase (ALAS) in heme biosynthesis. We report a 49-year-old male with severe microcytic anemia and ringed sideroblasts initially diagnosed as myelodysplastic syndrome (MDS). VB6 deficiency,

Zinc supplementation improves heme biosynthesis in rats exposed to lead

Universa Medicina, 2016
BACKGROUND Lead acetate (Pb) inhibits heme biosynthesis through inhibition of δ-aminolevulinic acid dehydrogenase (δ-ALAD), copro porphyrinogen oxidase, and ferro chelatase. Zinc supplementation increases lead-binding metallothionein proteins.

Neurodevelopmental Consequences Induced by Early‐Life Lead Exposure Through Disruption of Neurotransmitter Pathways and Molecular Mechanisms: A Systematic Review

Developmental Neurobiology, Volume 86, Issue 3, July 2026.
ABSTRACT Lead is a toxic heavy metal with significant health risks, as maternal lead exposure during pregnancy disrupts fetal neural development through placental transfer, leading to persistent neurological, developmental, and long‐term health consequences in the progeny.

Differential effects of lipid composition on the thermal and functional properties of membrane associated CYP2J2

Protein Science, Volume 35, Issue 7, July 2026.
Abstract CYP2J2 is a membrane‐bound cytochrome P450 that is expressed in cardiomyocytes, where it is known to metabolize arachidonic acid into cardioprotective epoxyeicosatrienoic acids (EETs). It consists of transmembrane domains embedded in the hydrophobic segments of the cell membrane and surrounded by various lipids.

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

ChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Hierarchically Engineered Multi‐Enzyme Nanoreactors for in vitro Drug Biosynthesis and Pathway Transplantation Into Cells

Advanced Materials, Volume 38, Issue 34, 17 June 2026.
A hierarchically structured metal–organic framework (eMIL) is shown to host the complete six‐enzyme biosynthesis pathway for the anti‐cancer pigment violacein, reshaping reaction dynamics and multiplying in vitro yields. eMIL nanoreactors deliver this reconstituted bacterial multi‐protein system into mammalian cells, where cell‐derived substrates and ...

Theranostic Advancements in Brain Cancer: Promising Approaches for Emerging Therapy

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Strategies for improving intra‐arterial administration (A) and photodynamic therapy in brain cancer (B). Improving intra‐arterial (IA) administration and photodynamic therapy (PDT) for brain cancer involves enhancing tumor targeting and breaching the blood–brain barrier (BBB). Key strategies include super selective catheterization, using osmotic agents
